News release: “For the third consecutive year the U.S. was home to the fastest-growing wind power market in the world, according to a report released today by the U.S. Department of Energy (DOE) and Lawrence Berkeley National Laboratory (Berkeley Lab). Specifically, U.S. wind power capacity increased by 46 percent in 2007, representing a $9 billion investment in new wind projects. At this pace, wind is on a path to becoming a significant contributor to the U.S. power mix: wind projects accounted for 35 percent of all new electricity-generating capacity added in the U.S. in 2007, and more than 200 GW (gigawatts, or billion watts) of wind power are in various stages of development throughout the country.”
